This article is interesting to read as most of the Semiconductor industry talks in India have been around Design and Manufucturing; very little around EDA.
1. EDA development in India: Yes, it is possible and it is happenning. I believe there is technical capability to develop new products. Some of the large players are already doing it.
Hence, it is possible for an Indian EDA company to grow and develop EDA product in India. But they would need to have a big size of their marketing outside India as the state of the art user are NOT yet in India.
2. Wafer Fabs: again a lot of hype going on but it will take 10-15 yrs to be able to do create the ecosystem to do state of the art. China, Malaysia and of course Taiwan, Singaproe are already there.
So this is really going to be the opportunity cost and the benefits of being located in India istead of else where: in term of profits, in terms of understanding the market for delivering for the Indian market.
Nevertheless, manufacturing is good for the economy as it allows a larger pool of employment with lesser qualitfication to earn more and Hence grow the economy.
3. High tech manufacturing and ATPkg: these would be where the first phase of manufacturing will come from and would be more viable as it requries lesser investment, lesser stringent infrastructure and easier to find or trian resources from the exisiting pool.
4. In any case: these are the years of OPPORTUNITY in INDIA for the ones who have the vision and the ability to sustain harship: in this century, the world will be supplied by China and India Or will be selling to China and India to make money out of their business.
